DETAILED DESCRIPTION OF THE EMBODIMENTS
[0043] Next, embodiments of the present disclosure will be
described in detail in conjunction with the accompanying drawings,
in which same or similar elements or elements having same or
similar functions are denoted by same or similar reference numerals
throughout. The following embodiments described with reference to
the drawings are exemplary, and are only for interpreting the
disclosure, but not for limiting the present disclosure.
[0044] In the liquid-crystal display in the prior art, a plurality
of color filter blocks are usually arranged on the side of the
color filter substrate facing the liquid crystal layer
corresponding to the pixels one by one, to convert light of the
backlight source into light of different colors. And the black
matrix is usually arranged between adjacent pixels, that is, the
display panel includes the pixel for displaying images and the
black matrix between the adjacent pixels, and not all of the
regions of the display panel are used for displaying. There is a
problem of a low efficient display region.
[0045] Referring to FIG. 1, embodiments of the present disclosure
provide a display panel, including a plurality of pixels 24
arranged in an array, and a black matrix 25 arranged between every
two adjacent pixels 24. Herein, the pixel 24 may be a red pixel 241
displaying red color, a green pixel 242 displaying green color, or
a blue pixel 243 displaying blue color. The display panel also
includes at least one display member 26 displaying a preset color,
and each of the at least one display member 26 is arranged between
two corresponding adjacent pixels 24 on a side of the black matrix
25 close to the light-outgoing surface of the display panel. In
FIG. 1, it shows that the display member 26 displaying a preset
color is arranged in a gap between two adjacent pixels 24 in any
row of pixels, the display member 26 is located on one side of the
black matrix 25 close to the light-outgoing surface AB of the
display panel.
[0046] In some embodiments, other parts of the display panel except
the display member 26 may be exactly the same as those of a liquid
crystal display panel in the prior art in structure, that is, the
display panel may include a backlight module 4 and a liquid crystal
cell above the backlight module 4. Particularly, the display panel
includes an array substrate 1 and a color filter substrate 2, and a
liquid crystal layer 3 arranged between the array substrate 1 and
the color filter substrate 2. Particularly, the color filter
substrate 2 may include a first base substrate 21 and a color
filter layer 20 arranged on a surface of the first base substrate
21 facing the array substrate 1, and the color filter layer 20
includes a plurality of color filter blocks corresponding to the
pixels 24 one by one (for example, the red color filter block
corresponding to the red pixel 241, the green color filter block
corresponding to the green pixel 242 and the blue color filter
block corresponding to the blue pixel 243). A black matrix 25 is
also arranged between every two adjacent color filter blocks.
Optically clear adhesive (OCA) 22 may be further arranged on the
display member 26, and an upper polarizer 23 may be further
arranged on the Optically Clear Adhesive 22. The array substrate 1
may include a second base substrate 11, a thin film transistor
layer 12 arranged on a surface of the second base substrate 11
facing the liquid crystal layer 3, and a lower polarizer 13
arranged on a surface of the second base substrate 11 opposite to
the liquid crystal layer. In order to not affect the manufacturing
of other layers of the color filter substrate, the display member
26 may be arranged on a surface of the color filter substrate 2
opposite to the array substrate 1, and located in the gap between
every two adjacent pixels of each row of pixels. That is, an
orthographic projection of the display member 26 on the
light-outgoing surface of the display panel overlaps the black
matrix 25 in the row where the display member is located on the
light-outgoing surface of the display panel.
[0047] In some embodiments of the present disclosure, the display
member displaying a preset color is arranged in the gap region
between every two adjacent pixels in any row of pixels.
[0048] Optionally, the display member may reflect ambient light
directly without need of the backlight source, such that the gap
region between the adjacent pixels of the display panel may also
participate in the display. Further, the effective display region
of the display panel may be improved, and the display member
displaying the preset color is arranged between the adjacent pixels
in any row of pixels, which may make the display panel display more
colors, and make the display smoother for achieving natural-color
display.
[0049] Particularly, the display member may include a first
electrode, an electrochromic layer, and a second electrode
successively arranged on the color filter substrate, and the
electrochromic layer displays the preset color when a preset
voltage is applied between the first and the second electrodes.
Particularly, the orthographic projection of the second electrode
on the color filter substrate overlaps with the orthographic
projection of the electrochromic layer on the color filter
substrate, the orthographic projection of the second electrode on
the color filter substrate also overlaps with the orthographic
projection of the first electrode on the color filter substrate,
and the orthographic projection of the second electrode on the
color filter substrate covers the orthographic projection of a gap
between the pixels adjacent to the second electrode on the color
filter substrate. Particularly, the first electrode may be made of
indium tin oxide (ITO) or graphene with high transmittance. For
example, considering the connection of process, the first electrode
is made of indium tin oxide. Particularly, the second electrode may
be made of indium tin oxide or graphene with high transmittance,
for example, considering the connection of process, the second
electrode is made of indium tin oxide. The electrochromic layer has
reversible color change characteristics subjected to a lower
driving voltage or current applied thereon, which refers to
reversible change in valence state and material component, such
that optical properties of the material will change or maintain
changing, and the electrochromic material also needs good ionic
conductivity, higher contrast, discoloration efficiency, cycle
period and other electrochromic characteristics. Particularly, an
electrochromic material may be an inorganic or organic
electrochromic material. The inorganic electrochromic material may
be tungsten trioxide, for example. At present, an electrochromic
device with tungsten trioxide as a functional material has been
already industrialized. And the organic electrochromic material may
be polythiophene and its derivatives, viologen, tetrathiafulvalene,
metallo phthalocyanines-type compound and the like. The
electrochromic material of vionlogen as the functional material has
already been applied in practice. Certainly, the material of the
electrochromic layer in the embodiment of this disclosure may also
be electronic ink which has been well known.
[0050] FIG. 2 is a schematic diagram of a vertical enlargement
structure of a region (such as the dashed line box 28 in FIG. 1)
where three adjacent pixels are located in FIG. 1. Each display
member 26 is arranged on a first base substrate 21 of the color
filter substrate, and further includes two first conductive
electrodes 261 arranged between the color filter substrate and the
first electrode 262 and contacting with the first electrode 262.
Each first conductive electrode 261 extends along a row direction
of the pixels, and is arranged between two adjacent rows of pixels,
and connected with an end of the first electrode 262. Each display
member further includes a second conductive electrode arranged on
the second electrode and contacting with the second electrode (not
shown in FIG. 2), and the second conductive electrode extends along
the row direction of the pixels, and is arranged between two
adjacent rows of pixels, and connected with an end of the second
electrode. In addition, In some embodiments, in the case where the
pixels include a red pixel, a green pixel and a blue pixel, the
display member may be a white display member displaying white
color. In a conventional display panel, successively adjacent three
pixels of the red pixel, the green pixel and the blue pixel are
usually used as a pixel group. Thus, correspondingly, In some
embodiments of the present disclosure, see FIG. 2, the first
conductive electrode 261 of the three display members corresponding
to every three adjacent pixels (such as the red pixel 241, the
green pixel 242 and the blue pixel 243 in the figure) is formed
integrally. That is, the display member corresponding to every
three adjacent pixels may be used as a display module to perform an
independent display so as to match with color requirements of each
pixel group. In some embodiments of this disclosure, the display
member is a white display member for displaying white color, thus
the display panel may increase brightness and achieve natural-color
display. But, this disclosure is not limited thereto.
[0051] An embodiment of this disclosure further provides a display
device, including the display panel provided by the embodiments of
this disclosure.
[0052] An embodiment of this disclosure further provides a
manufacturing method of a display panel in which the display panel
includes a plurality of pixels arranged in an array and a black
matrix between every two adjacent pixels. The manufacturing method
of the display panel includes:
[0053] forming at least one display member displaying a preset
color such that each of the at least one display member is arranged
between two corresponding adjacent pixels on a side of the black
matrix facing the light-outgoing surface of the display panel.
[0054] In some embodiments, the display member may be formed on a
color filter substrate. Particularly, a color filter layer and the
black matrix may be arranged on one surface of the color filter
substrate. After forming the color filter substrate, the display
member may be formed directly on the other surface of the color
filter substrate; and it is also possible that, after aligning and
assembling the color filter substrate and the array substrate, the
display member is formed on a surface of the color filter substrate
opposite to the array substrate. The following embodiment is
illustrated in combination with an example in which a material of
an electrochromic layer in the display member is electronic
ink.
[0055] As shown in FIG. 7, an embodiment of the present disclosure
provides a manufacturing method of a display panel, including step
1 to step 9.
[0056] At step 1, an array substrate is formed. The step for
forming the array substrate is the same as that in a method for
manufacturing an array substrate of a liquid crystal display panel
in the prior art, which will not be described herein.
[0057] At step 2, a color filter substrate is formed. The color
filter substrate is formed to include a plurality of color filter
blocks corresponding to the plurality of pixels, and a black matrix
between every two adjacent color filter blocks. The step for
forming the color filter substrate may be the same as that in a
method for manufacturing a color filter substrate of the liquid
crystal display panel in the prior art, which will not be described
herein.
[0058] At step 3, the array substrate and the color filter
substrate are aligned and assembled such that the black matrix is
located on a surface of the color filter substrate facing the array
substrate.
[0059] At step 4, a first conductive electrode 261 is formed on a
surface of the color filter substrate opposite to the array
substrate such that the first conductive electrode 261 extends
along a row direction of the pixels and is located between two
adjacent rows of pixels. A schematic diagram of the structure
formed with the first conductive electrode 261 is shown in FIG.
3.
[0060] At step 5, a first indium tin oxide electrode 262 is formed
in a preset region on the surface of the color filter substrate
opposite to the array substrate, and the preset region includes a
gap region between every two adjacent pixels of each row of pixels.
Herein, an end of the first indium tin oxide electrode 262 is
connected to the first conductive electrode 261. The schematic
diagram of the structure formed with the first Indium tin oxide
electrode 262 is shown in FIG. 3.
[0061] At step 6, an electronic-ink electrochromic layer 263 is
formed on the first indium tin oxide electrode 262. The schematic
diagram of the structure formed with the electronic-ink
electrochromic layer 263 is shown in FIG. 4.
[0062] At step 7, a second indium tin oxide electrode 264 is formed
on the electronic-ink electrochromic layer 263. The schematic
diagram of the structure formed with the second indium tin oxide
electrode 264 is shown in FIG. 5.
[0063] At step 8, a second conductive electrode 265 is formed on
the second indium tin oxide electrode 264, and the second
conductive electrode 265 extends along the row direction of the
pixels, and is located between every two adjacent rows of pixels,
and connected to an end of the second indium tin oxide electrode
264. The schematic diagram of the structure formed with the second
conductive electrode 265 is shown in FIG. 6.
[0064] At step 9, optically clear adhesive (OCA) is coated on the
second conductive electrode, and a polarizer is attached to the
OCA. Certainly, after attaching the polarizer, a packaging
protective layer of glass or PET may be further formed.
[0065] Herein, every three adjacent pixels (for example, the red
pixel 241, the green pixel 242, and the blue pixel 243 shown in
FIG. 6) arranged along the row direction of the pixels are
generally used as one pixel group. For one pixel group, as shown in
FIG. 6, the first conductive electrode 261 is arranged at two ends
of the pixel group as an integrated structure, and the
corresponding second conductive electrode 265 is also an integrated
structure and arranged opposite to the first conductive electrode
261.
[0066] As shown in FIG. 8, an embodiment of the present disclosure
provides a manufacturing method of a display panel, including step
1 to step 9:
[0067] At step 1, an array substrate is formed. The step for
forming the array substrate is the same as that in a method for
manufacturing an array substrate of a liquid crystal display panel
in the prior art, which will not be described herein.
[0068] At step 2, a color filter substrate is formed. The color
filter substrate is formed to include a plurality of color filter
blocks corresponding to the plurality of pixels, and a black matrix
between every two adjacent color filter blocks. The step for
forming the color filter substrate may be the same as that in a
method for manufacturing a color filter substrate of the liquid
crystal display panel in the prior art, which will not be described
herein.
[0069] At step 3, a first conductive electrode 261 is formed on a
surface of the color filter substrate opposite to the array
substrate such that the first conductive electrode 261 extends
along a row direction of the pixels and is located between two
adjacent rows of pixels. A schematic diagram of the structure
formed with the first conductive electrode 261 is shown in FIG.
3.
[0070] At step 4, a first indium tin oxide electrode 262 is formed
in a preset region on the surface of the color filter substrate
opposite to the array substrate, and the preset region includes a
gap region between every two adjacent pixels of each row of pixels.
Herein, an end of the first indium tin oxide electrode 262 is
connected to the first conductive electrode 261. The schematic
diagram of the structure formed with the first Indium tin oxide
electrode 262 is shown in FIG. 3.
[0071] At step 5, an electronic-ink electrochromic layer 263 is
formed on the first indium tin oxide electrode 262. The schematic
diagram of the structure formed with the electronic-ink
electrochromic layer 263 is shown in FIG. 4.
[0072] At step 6, a second indium tin oxide electrode 264 is formed
on the electronic-ink electrochromic layer 263. The schematic
diagram of the structure formed with the second indium tin oxide
electrode 264 is shown in FIG. 5.
[0073] At step 7, a second conductive electrode 265 is formed on
the second indium tin oxide electrode 264, and the second
conductive electrode 265 extends along the row direction of the
pixels, and is located between every two adjacent rows of pixels,
and connected to an end of the second indium tin oxide electrode
264. The schematic diagram of the structure formed with the second
conductive electrode 265 is shown in FIG. 6.
[0074] At step 8, the array substrate and the color filter
substrate are aligned and assembled such that the black matrix is
located on a surface of the color filter substrate facing the array
substrate.
[0075] At step 9, optically clear adhesive (OCA) is coated on the
second conductive electrode, and a polarizer is attached to the
OCA. Certainly, after attaching the polarizer, a packaging
protective layer of glass or PET may be further formed.
[0076] The beneficial effects of the embodiments of the present
disclosure are: by providing the at least one display member 26
displaying a preset color such that each of the display member 26
is arranged between two corresponding adjacent pixels 24 on a side
of the black matrix 25 close to the light-outgoing surface of the
display panel (for example, in FIG. 1, a display member displaying
a preset color is arranged in the gap region between every two
adjacent pixels 24 in any row of pixels), thereby the gap region
between the adjacent pixels of the display panel may participate in
the luminescent display, to increase the efficiency display region
of the display panel.
[0077] Obviously, those skilled in the art may make various
modifications and variants to this disclosure without departing
from spirit and scope of this disclosure. As such, if these
modifications and variants of this disclosure fall into the scope
of the claims and the equivalences of the disclosure, the present
disclosure intends to include these modifications and variants.
